Applicationiled September 6, 1905. Serial No. 277,213.

To a/ZZ whom it may concern:

Be it known that I, GEORGE F. THORN, av citizen of' the United States, and a resident of the cit of New York, borough of Manhattan, in t e county and State of New York, have invented-a new and Improved Column, of which the following is a full, clear, and exact description.

This invention relates to the construction of buildings, and especially to their framing.

The objectof the invention is to produce a column especially adapted for supporting floors and which is constructed of a plurality of sections placed one above the other.

A further object of the invention is to produce a construction at the point where these sections connect which will have great rigidity and durability.

The present case constitutes one of a series of copending applications which l have filed, including Serial N o. 283,099, filed October 17, 1905 l; Serial No. 29(),427,filed December 5, 1905, and Serial No. 298,116, filed January V27, 1906. These several cases embrace common subject-matter, and the matter common to all includes a column provided with a casing having a cap provided Witha recess above the body of the casing and which recess, together with the casing, contains a filling material, preferably of plastic nature, such as cement. The cap is apertured, and a rigidlyheld pin, post,l or other holding means projects from the aperture in the cap into the contiguous casin In severalof the cases referred to, including the forms shown in my present case and my applications Serial Nos. 283,099 and 290,427, a socket is provided to receive the end of the rod or post referred to.

The present case is founded upon the subject-matter which is common to all 'the cases referred to and also upon matterwhich is peculiar to the form shown in the present case. The invention consists in the construction and combination of parts to be more full described hereinafter and definitely set fortli in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate like parts in -both the figures.

Figure 1 is a central vertical section through the ends lof a column constructed according to my invention, certain parts being shown in elevation, others being broken away, as will appear; and Fig. 2 is a side elepoint between two sections thereof. This vjekw is substantiallya section on the line 2 2 o 1g. 1.

Referring more particularly to the parts, 1 represents Aa casing, which 'preferably consists of a cylindrical shell or tube. In practice this casing is preferably made of steel tubing. The column shown comprises three sections 1a, 1b, and 1C. placed end to end in erecting the column in the manner shown, the same being connected by joints 2 and 3. :The joints 2 and 3 are of similarconstruction, These joints comprise caps 4, preferably formed of cast-iron and presenting outwardly-projecting arms 5, adapted to support .the ends of beams 6 in the usual manner.. The bodies -of these Acaps are formed with downwardly-projecting necks 7 of reduced diameter, which are adapted to be receivedin the up er extremities of the casings, Las shown. y reason of the reduced diameter of the necks 7 a shoulder 8 is formed 'atthe lower ortion of the' bodyA of each cap. In this s oulder l provide-an annular, recess 9, which receives the upper extremity of the shell or casing, as indicated. In this waythe shoulder 8 constitutes a projecting lip, which overhangs or surrounds the extremity of thetubular shell or casing.

The necks 7 are formed each with a centrally-disposed recess 10 of enlarged diameter, and these recesses extend well up into the bodies of the caps. recesses are contracted slightly by lips 11,- wbich project in from the lower extremity of the necks, as shown. The principal portion of the wall of the recesses V10 tapers inwardly, as shown, se that the upper extremity is of slightly-reduced diameter. tions 12 of the recesses 10, which are formed in the body of the cap, are preferably of a uniform diameter, as indicated. The arms 5 are preferably braced by means of the usual webs or ribs 13, which connectl the under sides thereof with the bodies of the caps.

The upper plate or end of the cap or base is, as stated, formed with an aperture from which projects a means which connects or forms part of the connection between the cap or base and the column contiguous thereto.

Referring now to the particular form illustratcd herein, it will be noted that the aperture referred to does not extend entirely vation of a portion of my column, taken at a l through the cap and that in forming the caps These sections are The mouths of the- The upper por- IOO .4 each cap is provided with a pin 14, which projects upwardly from said aperture in the upper face of the cap, as indicated. It will be understood, however, that this is not essential to the generic invention. These pins are preferabl of steel, having enlarged heads 15, an in practice they are, in the form illustrated in this case, conveniently the casing, as indicated. These sockets 18' are forced into the ends of the casings, so that they aresecurely held therein, as will be readily'understood, 4the lower faces .of the sockets being flush with the lower ends of the casings, as indicated. Each of the sockets 18 is formed with a centrally-disposed bore 21, which is adapted to receive nicely one of The up er extremithe'pins 14, as shown. ties of the sockets 18 are refera ly provided each with a laterally-projecting lip 22.

The sections of the column are fitted one upon the other, asv indicated, and the bodies o the casings are completely filled with concrete or cement 23. When the bodies are being applied to the casings filled as suggested, the recesses 10 are preferably'filled with cement' 24, which as the caps are forced -into position completely fills the linterior y j thereof, so as to constitute a continuation of the filling of the body of. the casing. `When this cement and filling hardens, a very rigid connection exists between the cap and the Abody of the column, so that for all intents and purposes the cap becomes an integral part of the column-body. In this connection attention is called to the fact that the concrete interior or core projects well out beyond the upper edge of the casing, so as to constitute a solid core for the interior of the body of the cap.

Attention is also called to the shoulder 8,

and especiallyto' the utility of thelip, which .projects down at this point,so as' to surround the upper edge'of the casing. This hp operates to reinforce the upper end of the casing and prevents any tendency of the same to split or expand fromppressure upon thecap.

The column-section which is disposed above each cap is rigidly held in a'vertical position thereupon by reason of the steel pin 14, which projects up from the cap and is received in the sockets 18.

In practice I prefer that thev pins 14 should not extend entirely through theI upper extremities of the sockets; but I prefer to leave seams i With a column constructedas described the upper column-sections are self-supporting and rigid immediately when set up and do not in any way depend upo'n the beams for their support, though of course in practice the beams do operate to brace the columns against lateral displacement. With a column constructed as described the load is taken largely by the concrete filling, and the end of the tubular casing is reinforced by the shoulders 8, as described. The lower extremities of the casings'fit nicely in the recesses 17, 'so' that the sides of the recesses reinforce the lower extremities inthe same manner as the shoulders 8 reinforce the upper extremities thereof. In this way a very rigid column structure is produced.
